I picked up this buckle years ago at an estate auction along with some other odds and ends. At the time I thought it looked German or was a Flash Gordon toy or something. After some research it looks to be a German Youth buckle. So, what kind of value can I put on this if I'm going to sell it? I've seen them going for $130-$200 depending. I've been offered $70. It's in good shape. Any advice would be good.
